My invention relates to improvements in i conveyers.

In devices of this character employing an endless belt, it has been found that when material such as coal, sand, ashes and the like is A further object of my invention is to provide a simple and convenient flight for -aconveyer belt. I

I accomplish this object by the device illustrated inv the accompanying drawings, in which Figure 1 is a diagrammatic side elevation of a conveyer belt provided with my improved device, and

Figure 2 is a plan view of a portion of the belt.

Similar characters refer to similar parts throughout the several views.

The endless conveyer belt 1 is carried on pulleys 2, 3, one of which is the driving pulley and the other an idler.

The operation of devices of this character is well understood in the art and it is be lieved to be unnecessary to more particularly describe it.

The device is usually operated in an inclined position as shown in Figure 1 whereby material placed on the lower or receiving end of the device is carried by the moving belt to the upper or discharge end, from which it is discharged.

It becomes desirable, at times, to provide on the belt, a flight whereby the material being conveyed will be supported and prevented from rolling backward on the belt.

Devices of this nature are shown and described in the specifications of my Patents Nos. 1,422,398, 1,432,002 and 1,547,276.

The flights of my present invention perform the double function of flights to .assist in carrying the material and also covers 1927. Serial No. 205.314.

for the discharge apertures herein described. 1

I provide in the endless belt 1 a number of discharge apertures 4 preferably staggered as shown in Figure 2. r

Over these apertures 4, I provide covers 5 which are preferably of flexible material and which may be of the same material as the belt.

' These covers may be secured to the belt 1 by means of rivets 6 inserted through the cover 5 and belt 1 on the side of the discharge aperture 4 which on its operative side is toward the discharge end of the belt, the rear side or flap of the cover 5 being left free to open to permit the discharge of material.

The devicebeing thus assembled, the upper or operative face of the belt 1 will present the general appearance of the usual conveyer belt, the discharge apertures 4 being closed in the operation of conveying material.

Material which falls on the return side of the belt and which may find its way to the apertures 4 will, when of sufficient weight,

cause the covers 5 to open and will thus fall.

through the apertures 4.

Such material as may be carried by the return side of the belt to the lower pulley 3 will be collected in the apertures 4 and thereby carried around between the pulley 3 and the belt 1. i

The curvature of the pulley 3 will cause the covers 4 to open as illustrated at 4 in Figure 1, whereby the material will be ejected.

Having thus described my invention, what I claim is;

1, In a device of the character described, the combination of a pair of pulleys, an endless belt thereon adapted to convey material and having an operative upper portion and a lower return portion, discharge apertures in said belt, closure means for said apertures secured to the outer face of sa1d belt at one side of said apertures and having a free portion positioned over the aperture whereby material on the operative portion of the belt will be prevented from passing through said g apertures and said free portion being adapted 2. In a device of the character described, the combination of a pair of pulleys, an endless belt thereon adapted to convey material and being inclined from the horizontal and having an upper operative portion and a return portion therebelow, flights secured to the outertace of the belt, said flights having a tree portion and a fixed portion, apertures in the belt and lying below the tree portion of the said flights on the Operative portion of the belt and adapted to be closedthereby,

said free portion of the flights being adapted to open to permit the discharge through said apertures of material on the return portion of the belt. I

3. In a device of the character described,

" the combination of a pair of pulleys, an endless belt thereon adapted to convey material and having an operative portion and a return portion, cut-out apertures in the belt adapted to collect material carried to one of said pulleys by the return portion of the belt, closure means secured to the belt adjacent said apertures and adapted to be opened by the curvature of the pulley to discharge material collected between the belt and the pulley.
